Unified educational concept
The first thing you need to do now is to unify your thoughts. Including children's behavior habits, you decide what to change, which are minor problems, don't go into a dead end, and what ideas are inconsistent, so you need to continue to explore and solicit opinions. The consistency of educational ideas does not mean that you all agree that children should be taken care of, or that mothers are doing something wrong. The consistency of educational ideas should include ideas and methods.
Unified management method
You'd better unify management methods according to children's different behaviors. Your analysis of turning off TV is correct. Be sure to remind your child in advance and give him a chance. Because she is not an adult, she has poor self-control ability and needs a little training. At the same time, you can also train your child's concept of time in this matter. Like telling her to turn off the TV and take a shower in five minutes. Then remind several times in 5 minutes.
Mom should be strict.
There is also that mothers should be strict, gentle when they are gentle, and strict when they are strict. Strict doesn't mean fierce, strict is serious, so children are not easy to have rebellious psychology.
Children's behavior habits
Children don't necessarily cry on purpose, but subconsciously have different ways to deal with you in the process of behavior formation.
Parents' problems
You may have some questions, too. For example, you blame yourself after beating and scolding your child. To solve this problem, you must be clear about what you want to fight for. You are too excited to control anything. The ideal state when you hit her is that you are calm and have a clear purpose to hit her. When playing, be sure to let the child know why he was beaten. Besides, it's not good for girls to fight, so be careful. Otherwise rebellion will be more terrible than boys.
